A collaborative effort. Interesting, I like that idea.
I doubt inExile is a good choice, considering they are now hard at work with Numenera.
I'd rather say Obsidian would be a team to work together with, personally. Pillars of Eternity is almost finished, and nothing has come up to what the studio would be working on next.
I can see a beautiful, engaging and fun Sci-Fi RPG from Larian, especially if they work with people who have some experience in that field. Always, and I mean ALWAYS have wanted to definitive Steampunk or Dieselpunk RPG experience.
